Nice job. I did the same thing using a mount welded to the crossmember instead of a plate, or tray, mounted to the frame rails like you did.
I like your "tray" type mount better. More protection for the winch I'd think.
I haven't mounted the fairlead to the bumper yet, but am going to recess it into the front of my Hanson and use the winch platform for lights.
